The Chilean diplomático is a hearty sandwich of thinly sliced pork loin cooked with onion, oregano, salt, and pepper, topped with melted chanco cheese, and served in warm pan frica. It takes 4 hours of preparation, mostly chilling the meat for easy slicing, plus 30 minutes of cooking and serves 2 people.

Just as churrasco has the Barros Luco and ham has the Barros Jarpa, pork loin with melted cheese has the diplomático.

## How to Make a Chilean Diplomático?

The pork loin is chilled so it can be cut into very thin slices, cooked quickly with onion, portioned on the griddle, covered with cheese until melted, and piled into toasted bread.

1. Add the pork to the onions and cook over medium heat for about 10 minutes, separating the slices with a fork so they do not stick. Warm the pan frica on a griddle, in a toaster, or in the oven.

## Additional Tips

### Slice very thin

Chilling the loin makes it easy to cut thin slices that stay tender and juicy.

### Cook with moisture

Cooking the pork with onion, or a splash of stock, keeps it soft.

### Add vegetables

Lettuce, tomato, or extra onion give the sandwich a fresh twist.
